DESCRIPTION OF EMBODIMENTS

In the following, embodiments of the present invention will be describedin detail with reference to the drawings. The parts common to eachdrawing may be designated by the same reference numerals and descriptionthereof may be omitted. The scale of each member in each drawing maydiffer from the actual scale. In each drawing, the right and leftdirection (the longitudinal direction of the sheet package), the frontand back direction (the depth direction of the sheet package), and theup and down direction (the height direction of the sheet package) are inthe X direction, the Y direction, and the Z direction, respectively.

<Sheet Package>

FIG. 1 is a view illustrating a sheet package according to anembodiment. FIG. 2 is a diagram illustrating a sheet stacked body beforebeing stored in a packaging bag (before compression). FIG. 3 is a leftside view of FIG. 1 (a view of FIG. 1 in the X direction). A sheetpackage 100 according to the present embodiment includes a sheet stackedbody 10 and a packaging bag 20. As used herein, the sheet package refersto a package in which a plurality of sheets is packaged in a packagingbag. The sheet package 100 is an example of the sheet package accordingto the present embodiment.

The sheet stacked body 10 constitutes a sheet stacked body SL in which aplurality of (or a plurality of sets of) moisturizing sheets S isstacked (see FIGS. 1 and 2 ). As used herein, a moisturizing sheetrefers to a sheet in which a moisturizing ingredient is applied orimpregnated. Such a moisturizing sheet is also called a lotion tissue.

The moisturizing ingredient is not particularly limited, but forexample, a polyol is used. Examples of a polyol include glycerin,1,3-butylene glycol, propylene glycol, dipropylene glycol, tripropyleneglycol, diethylene glycol, triethylene glycol, hexylene glycol, andbenzyl glycol. Among these, glycerin is preferable. These polyols may beused alone or in combination with two or more. The additive amount ofthe moisturizing ingredient is freely decided.

Because the moisturizing sheet stores such a moisturizing ingredient,moisture in the air tends to be absorbed. Therefore, the sheet stackedbody made of a plurality of moisturizing sheets tends to absorb moisturedue to changes over time and collapse in a stacking direction, beingreduced in bulkiness. When the bulkiness of the sheet stacked body isreduced in the packaging bag, the packaging condition of the sheetstacked body may become unstable. As a result, the appearance of thesheet package may become deteriorated, or the stacking condition of thesheet stacked body may become disrupted in the packaging bag.

As used herein, the stacking direction refers to the direction SD inwhich the moisturizing sheets S constituting the sheet stacked body 10are stacked (see FIG. 1 ). In the present embodiment, the sheet stackedbody 10 is stored in the packaging bag 20 so that the stacking directionof the moisturizing sheets S (in the SD direction) is in the heightdirection (the Z direction). The sheet stacked body 10 is configured sothat the moisturizing sheet S can be pulled out one by one (or one setat a time) through a dispensing opening 21A formed on the top surface 21of the packaging bag 20 (see FIG. 1 ).

The sheet stacked body 10 is preferably one in which each moisturizingsheet S is stacked alternately in a folded state (what is known as apop-up type sheet stacked body 10) from the viewpoint of pulling out themoisturizing sheets S one by one or one set at a time. The configurationof the sheet stacked body 10 is not limited to one that can be pulledout in a pop-up manner, and may be one in which the plurality of (or theplurality of sets of) moisturizing sheets S is simply stacked, or one inwhich each moisturizing sheet S is stacked in a folded state.

The sheet stacked body 10 may have a length of 155 mm or more and 230 mmor less in the longitudinal direction (in the X direction) of the sheetpackage 100, a length of 90 mm or more and 120 mm or less in the depthdirection (in the Y direction) perpendicular to the longitudinaldirection (the X direction) of the sheet package 100, and a thickness of30 mm or more and 100 mm or less in the thickness direction (in the Zdirection). Such a stacked body of sheets may be manufactured, forexample, using a rotary or multi-stand inter folder.

The form of the moisturizing sheet S constituting the sheet stacked body10 is not particularly limited. For example, the moisturizing sheet Scan be applied to hygienic sheets such as tissue paper, toilet paper,kitchen paper, paper towels, and the like. The application of themoisturizing sheet S is not particularly limited. For example, themoisturizing sheet S can be applied to industrial, household, andportable applications. Among these, the moisturizing sheet S can besuitably used as a household tissue. The specification of themoisturizing sheet S (material, number of plies, basis weight,thickness, and the like) is freely decided.

In the packaging bag 20, the sheet stacked body 10 is packaged. Thepackaging bag 20 includes a top surface 21, a bottom surface 22, a frontsurface 23, a back surface 24, a side surface 25, and a side surface 26in a state where the sheet stacked body 10 is stored in the packagingbag 20. In the packaging bag 20, the top surface 21 and the bottomsurface 22 face in the up and down direction (in the Z direction), thefront surface 23 and the back surface 24 face in the front and backdirection (in the Y direction), and the side surface 25 and the sidesurface 26 face in the right and left direction (in the X direction).The side surface 25 and the side surface 26 are continuous with any ofthe top surface 21, the bottom surface 22, the front surface 23, and theback surface (see FIG. 1 ).

The dispensing opening 21A is provided on the top surface 21 of thepackaging bag 20. The dispensing opening 21A is configured so that themoisturizing sheet S can be pulled out. The form of the dispensingopening 21A is not particularly limited. The dispensing opening 21A maybe configured by, for example, a continuous cut, an elongated opening,and the like. In the present embodiment, a continuous cut is formed bybreaking perforations (intermittent cuts or cleavage cuts) (see FIG. 1).

The form of the packaging bag 20 is not particularly limited. Thepackaging bag 20 may be formed of, for example, a flexible film. Thematerial of the flexible film is not particularly limited, and forexample, resins such as polyethylene (PE), polypropylene (PP),polyethylene terephthalate (PET), polystyrene (PS), polyvinyl chloride(PVC), ethylene-vinyl acetate copolymer (EVA), polyamide (PA), and thelike may be used.

Among these flexible films, polyethylene, polypropylene, polyethyleneterephthalate, and the like are preferable from the viewpoint offlexibility, excellent handling, high sealability when heat-sealed, andlow cost. In addition, polyethylene is preferable from the viewpointthat it is odorless, excellent in water resistance and chemicalresistance, and capable of mass production at low cost. As thepolyethylene, a high-density polyethylene, a low-density polyethylene,and the like may be used. In addition, polypropylene is preferable fromthe viewpoint of being robust, being easy to shape, having good colordevelopment at the time of printing, and being able to impart gloss.

The form of the flexible film forming the packaging bag 20 is notparticularly limited. The packaging bag 20 may be a single layer film inwhich the resin is formed as a single layer, a laminated film in whichthe resin is laminated, or a mixed film formed of a mixture of two ormore of the resins described above.

The thickness of the flexible film forming the packaging bag 20 is notparticularly limited, and preferably 20 μm or more and 100 μm or less,and more preferably 25 μm or more and 70 μm or less. When the thicknessof the flexible film is 20 μm or more, it is possible to ensuresufficient strength as the packaging bag 20 in which the moisturizingsheet S is stored. Further, when the thickness of the flexible film is100 μm or less, it is possible to ensure flexibility and lightness ofthe packaging bag 20, and cost can be reduced.

The material forming the packaging bag 20 is not limited to the resinmaterial including the above-described flexible film and the like, and apaper material may be used. As the material forming the packaging bag20, a biodegradable material (biodegradable plastic, biodegradablepaper, and the like) and a biomass material (renewable biologicalorganic resources such as a biomass film excluding fossil resources) maybe used.

The packaging form of the packaging bag 20 is not particularly limited.In the present embodiment, for example, packaging in which both ends ofa tubular flexible film are folded and sealed (caramel packaging),packaging in which both ends or one end of a tubular flexible filmfolded into a gusset is sealed (pillow packaging), packaging in which aheat-shrinkable resin film is heated and brought into close contact withthe object to be packaged (shrink packaging), packaging in combinationthereof, and the like may be used.

In the present embodiment, the sheet stacked body 10 is packaged in thecaramel packaging (see FIG. 1 ). Specifically, the sheet stacked body 10is wrapped in a cylindrical shape by a flexible film such that both endsof the flexible film are opened in the longitudinal direction (in the Xdirection), and the portion overlapping in the wrapping direction of theflexible film is bonded by a fusion treatment or by using an adhesive.Then, both ends of the cylindrical flexible film in the longitudinaldirection (the X direction) are folded to the end face of the sheetstacked body 10. The substantially triangular or substantiallytrapezoidal pieces formed by the folding are overlapped at least at eachtip edge and bonded by a fusion treatment or using an adhesive to sealthe openings at both ends. In the present embodiment, both ends of thecylindrical flexible film (the side surfaces 25 and 26 of the packagingbag 20) are folded and sealed (see FIG. 1 ).

In the sheet package 100 of the present embodiment, the sheet stackedbody 10 is stored in the packaging bag 20 in a state of being compressedin the stacking direction SD at a compression rate of 50% or more and80% or less. The compression rate refers to the ratio of the stackedheight H2 of the sheet stacked body 10 (SL) after compression to thestacked height H1 of the sheet stacked body 10 (SL) before compression,when the sheet stacked body 10 is compressed in the stacking directionSD (see FIGS. 2 and 3 ).

In the present embodiment, the stacked height H2 of the sheet stackedbody 10 after compression in the stacking direction SD is lower than thestacked height H1 before compression (see FIGS. 2 and 3 ). When thestacked height H1 is set to 100%, the stacked height H2 is 50% or moreand 80% or less, preferably 55% or more and 75% or less, and morepreferably 60% or more and 70% or less. When the compression rateexceeds 80%, compression may be insufficient. When the compression rateis less than 50%, the packaging bag 20 may become damaged or may not besealed.

In the present embodiment, the sheet stacked body 10 in which theplurality of moisturizing sheets S is stacked is stored in the packagingbag 20 in a state of being compressed in the stacking direction SD at acompression rate of 50% or more and 80% or less. Accordingly, even whenthe moisturizing sheet S absorbs moisture due to changes over time, itis possible to prevent the bulkiness of the sheet stacked body 10 in thepackaging bag 20 from being reduced. Therefore, it is possible toprovide the sheet package 100 in which the packaging condition of thesheet stacked body 10 is stable.

In the present embodiment, because the sheet stacked body 10 is packagedin the caramel packaging, the sheet stacked body 10 compressed in thestacking direction SD at a compression rate of 50% or more and 80% orless can be easily stored in the packaging bag 20. Further, thepackaging bag 20 in which the sheet stacked body 10 compressed in thestacking direction SD at a compression rate of 50% or more and 80% orless is stored can be easily sealed.

In the sheet set package 200 of the present embodiment, five sheetpackages 100 (the sheet packages 101, 102, 103, 104, and 105), as theplurality of sheet packages 100, are stored in apposition in the setpackaging bag 30 (see FIG. 5 ). The manner in which the plurality ofsheet packages 100 (the sheet packages 101 to 105) is stored inapposition is freely determined. The plurality of sheet packages 100 ispreferably positioned in apposition in a state where the stackingdirections SD of the sheet packages 101 to 105 are matched (see FIGS. 1to 3, 5, and 6 ).

Here, “positioned in apposition in a state where the stacking directionsSD are matched” refers to a state where each of the sheet packages 100(the sheet packages 101 to 105) is positioned in apposition in adirection in which the stacking directions SD overlap (see FIG. 5 ). Inthe present embodiment, the stacking direction SD of each of the sheetpackages 100 (the sheet packages 101 to 105) matches the appositiondirection of each of the sheet packages 100 (the sheet packages 101 to105). The apposition direction refers to a direction JD in which theplurality of sheet packages 100 (the sheet packages 101 to 105)constituting the sheet set package 200 is arranged (see FIG. 5 ).

In the present embodiment, as illustrated in FIG. 5 , when the sheet setpackage 200 is positioned so that the holder 37 of the set packaging bag30 faces upward, a direction in which the plurality of sheet packages100 (the sheet packages 101 to 105) is arranged is the appositiondirection JD. In FIG. 5 , when the sheet set package 200 is positionedso that the side surface 35 faces downward and the side surface 36 facesupward, the height direction (the Z direction) is the stacking directionSD (the apposition direction JD) of the sheet packages 101 to 105.

In the sheet set package 200 of the present embodiment, the plurality ofsheet packages 100 (the sheet packages 101 to 105) is stored in the setpackaging bag 30 in a state of being compressed in the appositiondirection JD at a compression rate of 60% or more and less than 90%. Thecompression rate herein refers to the ratio of the apposition length L2of the plurality of sheet packages 100 (the sheet packages 101 to 105)after compression to the apposition length L1 of the plurality of sheetpackages before compression, when the plurality of sheet packages 100(the sheet packages 101 to 105) is compressed in the appositiondirection JD (see FIGS. 6 and 7 ).

In the present embodiment, the apposition length L2 of the plurality ofsheet packages 100 (the sheet packages 101 to 105) after compression inthe apposition direction JD is shorter than the apposition length L1before compression (see FIGS. 6 and 7 ). When the apposition length L1is set to 100%, the apposition length L2 is 60% or more and less than90%, preferably 65% or more and less than 85%, and more preferably 70%or more and less than 80%. When the compression rate is 90% or more,compression may be insufficient. When the compression rate is less than60%, the set packaging bag 30 may be damaged or may not be sealed.

In the sheet set package 200, the sheet stacked body 10 made of theplurality of moisturizing sheets S tends to be reduced in bulkiness dueto changes over time as described above. When the bulkiness of the sheetstacked body 10 constituting each of the sheet packages 100 (the sheetpackages 101 to 105) is reduced in the set packaging bag 30, thepackaging condition of each of the sheet packages 100 (the sheetpackages 101 to 105) may become unstable in the sheet set package 200.As a result, the appearance of the sheet set package 200 may becomedeteriorated, or when the plurality of sheet set packages 200 is stackedon display and the like, the plurality of sheet set packages 200 maybecome largely inclined and toppled over (see FIGS. 11 and 12 ).

In contrast, in the present embodiment, as described above, theplurality of sheet packages 100 (the sheet packages 101 to 105), inwhich the sheet stacked body 10 compressed in the stacking direction SDat a compression rate of 50% or more and 80% or less is stored, isstored in the set packaging bag 30. Accordingly, even when themoisturizing sheet S absorbs moisture due to changes over time, it ispossible to prevent the bulkiness of each of the sheet packages 100 (thesheet packages 101 to 105) in the set packaging bag 30 from beingreduced. Therefore, it is possible to provide the sheet set package 200in which the packaging condition of each of the sheet packages 100 (thesheet packages 101 to 105) is stable.

In the present embodiment, when the plurality of sheet set packages 200is stacked, it is possible to prevent the plurality of sheet set package200 from being largely inclined in a stacked state or toppled over. Forexample, as illustrated in FIG. 8 , when the plurality of sheet setpackages 200 (the sheet set packages 201 to 212) is stacked, the stackedstate is maintained almost as it was when it was stacked, or slightlyinclined, even one week after stacking (see FIGS. 9 and 10 ).

In the present embodiment, as described above, the plurality of sheetpackages 100 (the sheet packages 101 to 105), which stores the sheetstacked body 10 in which the plurality of moisturizing sheets S isstacked, is positioned in apposition in a state where the stackingdirections SD are matched. The plurality of sheet packages 100 (thesheet packages 101 to 105) is stored in the set packaging bag 30 in astate of being compressed in the apposition direction JD at acompression rate of 60% or more and less than 90%. Accordingly, evenwhen the moisturizing sheet S changes over time, it is possible toprevent the bulkiness of each of the sheet packages 100 (the sheetpackages 101 to 105) in the set packaging bag 30 from being reduced.Therefore, it is possible to provide the sheet set package 200 in whichthe packaging condition of each of the sheet packages 100 (the sheetpackages 101 to 105) is stable.

In the present embodiment, the plurality of sheet packages 100 (thesheet packages 101 to 105) is stored in the set packaging bag 30 in astate of being compressed in the apposition direction JD at acompression rate of 60% or more and less than 90%. Accordingly, when theplurality of sheet set packages 200 is stacked, it is possible toprevent the plurality of sheet set packages 200 from being largelyinclined in a stacked state or toppled over (see FIGS. 9 and 10 ).

In the present embodiment, as described above, in the plurality of sheetpackages 100 (the sheet packages 101 to 105), the sheet stacked body 10compressed in the stacking direction SD at a compression rate of 50% ormore and 80% or less is stored in the packaging bag 20. The plurality ofsheet packages 100 (the sheet packages 101 to 105) is positioned inapposition in a state where the stacking directions SD are matched andis stored in the set packaging bag 30 in a state of being compressed inthe apposition direction JD at a compression rate of 60% or more andless than 90%. Accordingly, even when the moisturizing sheet S changesover time, it is possible to prevent the bulkiness of each of the sheetpackages 100 (the sheet packages 101 to 105) in the set packaging bag 30from being reduced. Therefore, it is possible to provide the sheet setpackage 200 in which the packaging condition of the plurality of sheetpackages 100 (the sheet packages 101 to 105) is stable.

In the present embodiment, the plurality of sheet packages 100 (thesheet packages 101 to 105) is stored in the set packaging bag 30 in astate of being compressed in the apposition direction JD at acompression rate of 60% or more and less than 90%. Accordingly, when theplurality of sheet set packages 200 is stacked, it is possible toprevent the plurality of sheet set package 200 from being largelyinclined in a stacked state or toppled over (see FIGS. 9 and 10 ).
